Victorian illustration to download showing Hornsby’s portable agricultural steam engine, which won a prize at the Royal Agricultural Society’s meeting in York, 1848. A 6hp engine, it could be used for threshing and other agricultural tasks. Richard Hornsby (1790-1864) founded Richard Hornsby & Sons, engine and machinery manufacturers, of Spittlegate Ironworks, Grantham. This steam engine was one of their most important products and a market leader. Hornsbys produced the first oil-engined tractor in Britain in 1896, and pioneered caterpillar-tracked machines.
